J1 VAPYVPYARATUS-FOR TREATING HYDBQCARBONS.

To all wko 'm it mag cbmemf Beit known'that'we", FRANK L.- SLocUM andCHARLES C1 STUTZ, residing: at Pittsburgh," in the county of Alleghenyand State of- Pennsylyania', citizens of the United States, haveinvented or "discovered certain new and usefulv ImprovementsinApparamoval and "segregation-of carbon formed during. the treatmentwithout interruption l to continuity of'the operation. The invention ishereinafter more fully described and claimed.- The cracking process towhich the apparatus,is particularly applicable is fully described inBulletin 114, Petroleum TechnoZogy29fDepartment,ofthe Interior h he eeoipanr dr i forming a part of thisspecification, Figure l is an elevationof an apparatus embodying our improvements as applied to a plurality ofcracking'tubes,and Rig. 2is a sectional elevationshowing the'lowerportion of a cracking tube and chamber into which the various'productsformedfin the tube are discharged." P I i ,As shown in Figs. 1 and '2,the lower side of the "cracking tubes:v 1 'are secured to a casting; ini which isfformed a chamber 2, directly under: the tube so that thecarbon,

1 Specification of Letters Patent. Patented May 20, 1919;

the tube and the chamber, and in orderto prevent the carbon, etc.,discharged from the open lower end of the tube, from-adher ing to thetube surrounding the driving shaft and as far as possible to passdirectly to the bottom of the chamber 2, a distributer' preferably inthe form of an umbrella shaped casting 4 is arranged below the openlower end of the tube 1 and is in the normal operas tionof the machine,supported by the" upper end of the driving" shaft 7 so as to rotatetherewith- When the driving shaft and its l inclosing tube'are removedthe umbrella will be supported by the sleeve 10. a The chamber 2 isprovided adjacentt and vapors generated in the .tubel, said outlet beingadapted to be-conne'cted'with its upperend, with an outlet'13 for gasessuitable condensing apparatus; Atits lower end, .the chamber 15providedwith two valved outlets 14 and '15,for the discharge *i ofcarbon and liquid products. .As shown in Fig; 1 one of the valvedoutlets is-"c'on nected by a pipe 16 to a chamber-'17-arid the otheroutlet by a pipe 16, to a chamber:

17?. These pipes are so- 'connected to the; segregating chambers 17 and17 ,as to dis? charge the mingled carbon. and oil into one 1 end oftroughs 18 and 18 which are divided into compartments by baflleplates'l9 and 20. As the liquid and the carbon are discharged into the.first compartment, the

greater part of the latter will settle-down" therein, but theoil-willfflow over the "baffle 19 into the second "compartment,iwh'erein carbon, carried -:by' the oil overthe first baflie, ,yvillsettle. down. The bottom of the third-f compartment is perforated toallow the Iliquid V to drain out into 2 the chambers fromawhich it isdischarged, through the;

re r d ou l 1 'is closed, and the valve in the outlet connected' to theother troughs containing cham- Whe cre tor the-troughshas been sufii heris opened. As soon as the valve'controlling flow to the first chamber isclosed,

carbon removed, and the trough returned to the chamber. 'Beforeremovingthe head from*the chamber, the liquid contained therein is discharged.

As the carbon, etc., may adhere to he surface of the umbrella, or becomelodged in the chamber 2 or in the pipes leading therefrom, provision ismade for cleaning the umbrella and washing along any carbon which mayhave lodged in any portion of the apparatus, by means of jets of oilresulting from the condensation of vapors flowing from tube 1.

In the construction shown, a pump diagrammatically represented at 21, isconnected by'a pipe 22 to the segregating chamber 17, and to thesegregating chamber 17, by a pipe 23, the pipes 22 and 23 being provvided with valves so that when one of the chambers is to be opened forthe removal of its trough, the connection between the chamber and pumpmay be closed. The discharge port of the pump is connected to a pipe 24,having a series of branches, 25, 26 and 27, the branch 25 having avalved connection'28 to the upper portion of the collecting chamber, theconnection 28 being so arranged as to direct a stream of liquid onto thesurface of the umbrella. The branch 26 has a valved connection 29, tothe lower portion, of the collecting chamber, the connection being soarranged as to wash the carbon, etc., into the trough through theout-lets 14.-and 15.

As shown, a plurality of tubes 1 and collecting chambers have theiroutlets 14 connected to a common pipe 30. and the outlet 15 to a commonpipe 31, said pipes 30 and 31 being connected respectively to the pipes16 and 16? as shown in Fig. 1. IVhen a plurality of chambers are thusconnected to pipes 30 and 31, the branches 25 and 26 from the main pumpline 24, have valved connections 28 and 29 to the other collectingchamber 2 and the branch 27 is so connected to the ends of the commonpipes 30 and 31 as to wash the carbon toward and into vertical pipes 16and 16.

As the tube 1 discharges into the chamber 2, the latter will containgases and vapors and while the material is subjected to such conditionsin the tube 1 as are most favorable for the production of particulartype of hydrocarbons, having certain characteristics and a certainboiling point, hydrocarbons having other and higher boiling points willalso be produced. In order to effect a partial segregation of thehydrocarbons, in acrdance with their boiling points. it is preferred toso reduce the temperature of the provided with an outlet for the escapeof gases and vapors, and an outlet" for the removal of solids andliquids, and means for returning discharged liquids to said cham ber toinsure the removal of the solids.

means for removing deposits from the walls of the said tube, a chamberfor the reception of material discharged from said tube, said chamberbeing provided with an outlet for gases and vapors and an outlet for theremoval of solids and liquids, means for reducin the temperature of saidchamber below the boiling point of a portion of the vapors dischargedfrom the treating tube, and means for returning discharged liquid tosaid chamber to insure the removal of the solids therefrom.

3. In an apparatus for cracking hydrocarbons, the combination of atreating tube, means for removing deposits from the inner surface ofsaid tube, a chamber for the reception of material discharged from saidtube, said chamber being provided with outlets for the removal ofproducts received from the tube, means for segregating the solids andliquids removed from the chamher, and means for returning liquid tothechamber to insure the removal of the solids.
